Title: Multiple alarm condition detection and signalling
IPC: G08B29/06
Filed: 1980-12-05
Abstract: A security system has a locality station A or B sensing security risks such as fires, electrical faults and break-ins, being powered by a single line 1, 1a from a central station 26. The loading on the power supply 27 is determined by logic circuits 30 to give direct remote indications of the security state at the locality station. The power is supplied as a square wave which is altered 28, 29 in waveform to give alternative commands to the locality station, e.g. to sound a warning Y or to operate a fire sprinkler Z, while continuing to supply power, eg. at C. To enable maximum use of the single line and single square wave, the latter is treated as two separate signals in that loading by the locality station is selective e.g. 5A, 5B as regards the polarities. Similarly the alternative commands available are doubled by using separate control of the durations of the positive and negative square wave portions. The positive and negative durations may have separate evaluation units, 12, 14 and 13, 15 at the locality station. Whatever the durations selected and evaluated, power continues to be supplied by the square wave train. <IMAGE>

Title: Microprocessor watchdog system
IPC: G06F11/00
Filed: 1981-06-30
Abstract: A watchdog system for a microprocessor (14) uses the primary AC power source to initiate restart signals for the microprocessor (14). The microprocessor (14) has an internal checking system. If a check is satisfactory, the microprocessor (14) provides a reset signal (18) at regular intervals to a counter (15) coupled to the primary AC power source which counts the pulses it receives until a predetermined count is reached. The counter (15) then provides a restart signal (16). The counter (15) is reset by the reset signal (18) from the microprocessor (14) when the check is satisfactory, and the time interval between reset signals is shorter than the time required for the counter to count to the predetermined count. The microprocessor (14) may check that a predetermined valve is present is a specified memory location therein. <IMAGE>

Title: Adjustable striker for locks
Inventor: HIBBERT ERIC
IPC: E05B15/02
Filed: 1981-11-21
Abstract: The striker comprises a strike block 1 having a stepped abutment 3 for engagement by the hook end of a bolt.

Patent GB-2091003-A (GB)
Title: Magnetic seal system
IPC: F16J15/34
Filed: 1981-11-23
Abstract: A seal frame position control system has displacement-sensing transducers (100) which sense changes in the sealing gap between a rotating seal frame 4 and the stationary axial end face 7 of a matrix (6) of a regenerative air preheater. The sealing gap varies due to thermal distortion of the matrix (6). When this happens, the transducers (100) control the energisation of electromagnetic devices 15 which are attached to the seal frame 4 and cause axial movement of the frame 4 relative to the axial end face 7 of the matrix (6). In this way the gap is maintained at a constant value, thereby minimising seal wear and leakage. There are a plurality of electromagnetic devices 15 spaced round the periphery of the frame, each one, or each group, with its own transducer which affects control by adjusting the triggering point of thyristors in bridges which supply the devices 15. The weight is partially supported by springs. <IMAGE>

Title: Sliding roof for vehicle
IPC: B60J7/05
Filed: 1981-11-25
Abstract: The sliding roof panel (1) has a backwardly and upwardly inclined ventilating position. The panel (1) is supported near its front edge by links (25 and 26) which are connected with a front slide shoe (9). The links ensure that the forward part of the panel is moved upwards and backwards when the panel is displaced from the closed position to the backwardly and upwardly inclined ventilating position, thereby avoiding risk of damage to the front seal (6). <IMAGE>

Title: Display arrangements
Inventor: NIXON R D
IPC: G09F9/30
Filed: 1981-11-26
Abstract: A display arrangement consists of one or more elongate display devices, each of which has a number of separately energizable display areas positioned along its length. When energized, each display area is seen as a bright patch of light. As it is very difficult to arrange that the display areas extend right to the extreme ends of the device, optical deflection means are positioned in front of the display areas to magnify the size of each so that the total display area extends over the whole length of the elongate display device. The optical deflection means is arranged so that each bright patch is of substantially the same size. The invention enables a large number of similar elongate display devices to be placed end to end while avoiding the appearance of periodic dark patches at the ends of adjacent devices.

Title: Flue arrangements for boilers
Inventor: WHITE MARTIN
IPC: F28F1/40
Filed: 1982-03-01
Abstract: A fuel-fired fluid heating appliance, such as a gas-fire boiler includes a flue 4 for discharging the combustion products, eg. exhaust gas, to atmosphere by way of a heat exchanger 8 incorporated within a portion 6 of the flue 4 external of the boiler housing 1. The heat exchanger 6 is provided with an inlet 16 to receive water from a return flow pipe 36 and an outlet 17 to discharge the water to the inlet 36 of the boiler primary heat exchanger 3. Exhaust gas travels along ducts 18 to transfer its heat to the water circulating within compartments 29 to 33 within the heat exchanger housing 15. To increase thermal efficiency, the external portion 6 of the flue 4 is disposed at an angle of 20 DEG  downwardly to the horizontal so that any exhaust gas condensing in the heat exchanger 8 flows down the flue base 9 to a discharge spout 10 and a collector weir 11. In an alternative arrangement, the flue portion 6 slopes upwardly and an outlet for condensed gases is provided externally of the boiler housing. <IMAGE>

Title: An improved overhead electric transmission or distribution system
Inventor: GAYLARD B
IPC: G02B6/44
Filed: 1982-06-15
Abstract: Risk of fracture of an optical fibre loosely housed in an elongate compartment extending throughout the length of an overhead stranded conductor 1 when the conductor is subjected to a tensile load greater than that which the optical fibre is designed to withstand is reduced by supporting the stranded conductor from each of two opposite sides of a tower 2 by suspension means 3 incorporating a weak link 4 designed to fracture at a tensile load less than that which the optical fibre can withstand. An excess length 6 of the stranded conductor extends between fittings 5 at which the suspension means 3 are secured to the conductor 1 and, where the stranded conductor is an earth conductor, is detachably secured to the tower at spaced positions along its length by releasable clips 7. When the load on conductor 1 increases, a weak link 4 will fracture and the excess length 6 of stranded conductor will be detached from the tower to reduce the load on the conductor and thereby reduce risk of optical fibre fracture. <IMAGE>
